We bought a router and 1 point system at the beginning of the pandemic. It worked fine for about a year. Now for months I've been having a dropped network issue every few days. It was enough to make me switch ISPs, but the issue still persists. This confirms a hardware issue with either the Google router or point or both. It seems this is a known issue and Google has done nothing to address it. I'd be willing to try a new point to see if that solves the problem, but Google should offer a replacement for free.
Here's one recent article that supports this being a known issue. https://9to5google.com/2022/04/14/nest-google-wifi-offline-random/
It happened again over the weekend and I just disconnected (and factory reset) the point. My router is hard-wired to the fiber connection, so in theory it should NEVER drop. So far it's been rock solid. The router by itself should power my whole house (according to Google specs) so the point was really just for reinforcement/extended coverage outside anyway. Still, if it's a known hardware/firmware issue, Google needs to offer replacements.
I'm sorry for the issues you're seeing with your connections. I know it's frustrating when things lack stability. We have seen a few other users with this issue, and there are a few different things you can try to settle things. The first thing I would check is to see if you have IPv6 enabled in the Home app WiFi settings. If you have IPv6 turned on, trying turning it off and see how it impacts things. If you continue to have issues at that point, let me know and we'll go to additional steps.
See thread below and good luck.
I Chased my nest wifi issues for months. It's the Nest wifi router. My 1gb internet service was absolutely unusable on this router and it started 4 or so month ago. Worked fine for almost 2 years then 4 months ago wired connections were fine but wifi was unusable. Gave up after months of no support from Google on this issue. See similar stories below
